Detector for equal color tone region

Abstract

Abstract PURPOSE: To make regions of equal color tones detectable with respect to all color tones contained in the images to be measured by storing the signals by hues by a scanner beforehand. CONSTITUTION: Artibrarily specifiable positions of images 1 are assigned by using a scanner generating the signals by hues in respective parts by scanning the images 1 to be measured and the signal levels from the device 2 are stored as shown at 12W14. The levels of the respective signals by hues in the respective parts obtained by the subsequent scanning are compared as shown at 6W11 with the stored levels. Equal color tone areas are detected as shown at 28 in accordance with the principle that the color tones of the scanned parts where the levels are equal are equal to the color tones of the positions assigned beforehand.
